MATERIALS AND METHOD TO SEAL VIAS IN SILICON SUBSTRATES

摘要

Sealing a via using a soventless, low viscosity, high temperature stable polymer or a high solids content polymer solution of low viscosity, where the polymeric material is impregnated within the via (100) at an elevated temperature, A supply chamber (630) is introduced to administer the polymeric material at an elevated temperature, typically at a temperature high enough to liquefy the polymeric material. The polymeric material is introduced through heated supply lines under force from a pump, piston, or a vacuum held within said supply chamber.
